Pelikan Edelstein Bottled Ink for Fountain Pens, Aventurine Green, 50ml, 1 Each (339366)

Ink was very fluid and smooth, one of my favorite colors from this collection. Very good quality ink, plus the easy close screw on cap keeps the ink safe.

These German sellers of Edelstein are lifesavers. Pelkikan Edelstein ink is spectacular, but insultingly overpriced in America. For $30, this ink is forgettable. For under $20, this stuff is a rocking deal. The bottles are awesome (not the most practical, but far from the worst, and they look amazing on any desk, with jewel like glass and a beautiful cap) And the ink is just stellar.Medium flowing, medium-high saturation, some red sheen (reviewing Topaz) decent manners on bad paper, well behaved on good paper, decent dry times, it's just a lovely color in a lovely bottle. Shipping was exceptionally fast for international (less than a week for every bottle I've ordered from a german seller) and I just can't find a reason to suggest you don't buy a bottle. Some of the colors can be a little underwhelming, but Topaz is definitely one of the more exciting colors. Not much water resistance though.If you can find a bottle of Smoky Quartz for this price, jump all over it. THAT stuff is something special.

I bought this ink for its beautiful color — it's suitable for work, but still distinctive. I've been impressed with its consistent performance in all of my pens: It flows nicely and creates lovely shading without being too wet. It dries pretty quickly too and does okay even on cheap copier paper (some bleeding, but not terrible). Like most blues and dye-based inks, it's not very water resistant. But that's about the only caveat i can think of. It's a great value considering the large size of the bottle, and i won't hesitate to buy it again.

The color is fantastic, viscous texture, yet no clogging.Great quality glass vial if you care about this.

I use this ink for all my fountain pens, antique as well as new. Beautiful color, the ink glides. Very happy with it. Very happy with the quality, ease of cleaning ? It’s an ink… it does flow well. It is a great medium dark blue.

I bought a bottle of Pelikan Edelstein Tanzanite along with a few colors from other manufacturers in an attempt to replace the original Pelikan Blue-Black. The U.S. Food and Drug Administration banned the import of Pelican Blue-Black in 2011 citing a key ingredient, dihydrogen monoxide (DHMO). Apparently this is in all iron gall inks, and Lamy and Montblanc inks with this ingredient have also been banned.The two key issues in comparing the new Edelstein and the old Blue-Black are color and ink flow. First color. Pelikan Blue-Black was a neutral medium-dark gray ink with a bluish hue. The overall impression was of grey first and then blue. Compared to Parker Quink blue-black it wasn't blue at all. I think both inks were classic colors, Quink for letter writing from the 1950s and 1960s, Pelikan for diary entries and sketches going back to the 1920s. Tanzanite is neither as neutral as the old blue-black nor as blue as the Quink. Tanzanite is definitely a blue ink, best suited for letter writing or for use in a nice broad signature pen. It is a bold color, much darker than the old blue-black, and the blue hue shades a little toward red. Don't worry, it is nowhere near purple.Ink flow. Regular users of Pelikan inks know that they tend to be quite dry in relation to other manufacturers' inks. This is a matter of both personal taste and the age and type of nib used. I use pens dating from brand new back to the early 1910s, and certain pens in my collection dry up quickly when I put Pelikan inks in them. With their new Edelstein inks, Pelikan has included a very effective lubricant. In pens with very dry-writing nibs it allows writing without drying out or scratching. In pens with fast flowing nibs it does not increase the flow to the extent that a fine point suddenly writes like a broad. I have no idea how they accomplished it but I think this is the genius of the entire Edelstein line.To sum up: Pelikan has come out with a new line of well-designed inks. As befitting new inks, none (except for Onyx, black) is the same color as a previous Pelikan ink. Working under constraints put on them by the federal government, Pelikan had to drop their iron-gall based blue-black ink entirely. Pelikan has engineered a new lubricant which allows scratchy pens to write well while not increasing the flow of wet-writing pens. All in all I think the Pelikan Edelstein range is a good new product line, and Tanzanite is a good color. Remember, Guenther Wagner started Pelikan as an ink company in the 19th century, so it is good to see they are still innovating.My one wish is that they come out with a 1-ounce bottle in the new design.

Since the pictures on Amazon don't include any photos of the color itself, this is an absolutely gorgeous, stunning bright vibrant cerulean blue. It's bluer and darker than a cyan, but not quite as dark as a standard formal blue. I have a ridiculous number of blue inks that pretty much span the spectrum of shades, and I don't have anything even a little bit like this.I am a true connoisseur of inks, and especially blue inks since I have to use them for work. I thought I'd tried them all - everything from the most expensive of Japanese inks to the cheapest brand X standards. This beautiful blue excels in every category - I've used it extensively on both Rhodia and Moleskine paper, and it doesn't bleed or feather through either, even in my wettest pen. Dry time is excellent as well.OK enough with the boring stuff, let's get on to what you really buy an ink for: the sheer beauty of it! I am in love with inks that shade, and oh my goodness the shading on this is even better than my previous favorite Kensington Blue. Oh the shading. Even in a stiff, cheap converted Preppy, this ink gives amazing shading.Overall, I can't recommend this enough - worth every penny for a dazzling, unique blue ink of outstanding quality.

Nice flow and color. Fancy bottle. Sort of a dark turquoise.
